Warning: Spoilers for Black Clover chapter #361Lucius Zogratis revealed his overpowered new magical abilities in Black Clover and they basically make him unbeatable, even by someone who is technically stronger such as Yuno. On the surface, Lucius' power to create endless clones of himself might seem completely random and just a little too serendipitous for the sake of creating additional conflict, but the series has been laying out the foundation for these new powers for quite some time now, and they come from the best sources possible.
